the area of the circle is 64pie cm square find the length of its arc subtending an angle of 60 degree at the center and also the area of coresponding sector

Question

its maths quations about trigonometry area

Answer 1

64π = πr²

8 = r

C = 16π

60° = (16)(l360°)

arc length = (1/6)16π

area sector = (1/6)64π
